贵州某低品位含碳难选冶金矿选矿工艺

Beneficiation of a Low-grade Carbonaceous-arsenic Bearing Refractory Gold Ore in Guizhou

针对贵州某低品位金矿含砷、有机碳等有害杂质,且含金矿物呈微细粒嵌布,为典型的卡林型金矿石。通过矿石性质研究、工艺矿物学研究及前人试验研究的调研,开展条件试验和多种选别流程的对比试验研究,该试验研究获得金精矿金品位19.18 g/t,金回收率91.61%。

A low-grade gold ore in Guizhou province is a typical carlin type gold deposit, which is carbonaceous- arsenic bearing and free-grained disseminated gold ore. The test study was carried out based on the research of ore property, process mineralogy and previous experimental works. The experimental research shows that the gold concentrate has a gold grade of 19.18 g/t at a gold recovery of 91.61%.
